Implementation of a unified userspace time handling library under the Linux OS

An appropriate assessment of end-to-end network performance presumes highly efficient time tracking and measurement with precise time control of the stopping and resuming of program operation. In this paper, a novel approach to solving the problems of highly efficient and precise time measurements on PC-platforms and on ARM-architectures is proposed. A new unified High Performance Timer and a corresponding software library offer a unified interface to the known time counters and automatically identify the fastest and most reliable time source, available in the user space of a computing system. The research is focused on developing an approach of unified time acquisition from the PC hardware and accordingly substituting the common way of getting the time value through Linux system calls. The presented approach provides a much faster means of obtaining the time values with a nanosecond precision than by using conventional means. Moreover, it is capable of handling the sequential time value, precise sleep functions and process resuming. This ability means the reduction of wasting computer resources during the execution of a sleeping process from 100% (busy-wait) to 1-1.5%, whereas the benefits of very accurate process resuming times on long waits are maintained.

Resposta da assembleia de formigas na interface solo-serapilheira a um gradiente de alteração ambiental

O estudo objetivou avaliar a resposta da assembleia de formigas que nidificam na interface solo-serapilheira a um gradiente de alteração ambiental. O estudo foi realizado em três ambientes com diferentes usos do solo: fragmento florestal, sistema agroflorestal (SAF) e pastagem situados em região de domínio da mata atlântica no sudeste do Brasil. Em cada ambiente foram demarcadas 10 parcelas de 1 m² e todos os ninhos de formigas encontrados foram registrados. Foram encontrados 215 ninhos (103 no fragmento florestal, 64 no sistema agroflorestal e 48 na pastagem), de 31 espécies. O número acumulado de espécies foi maior no fragmento florestal que na pastagem, mas não diferiu do SAF. A composição de espécies foi diferente entre o fragmento florestal e os outros dois ambientes. A riqueza média de espécies de formigas por parcela foi maior no fragmento florestal e menor na pastagem. A quantidade de serapilheira não foi um fator importante para as diferenças na riqueza de espécies. Atividades humanas que reduzam a heterogeneidade da vegetação alteram a composição e diminuem a riqueza de espécies das assembleias de formigas.

Simulació d'arquitectures VLIW

L'objectiu d'aquest projecte es dissenyar i implementar en Java una interfície gràfica que permeti simular l'arquitectura VLIW. Ha d'interactuar amb un simulador ja existent, VEX, i amb l'usuari. VEX permet analitzar, desenvolupar i depurar codi escrit en C sobre un processador VLIW configurable, des dels recursos hardware fíns al comportament de la "caché". L'interfície gràfica desenvolupada es diu JavaVEX. Té el gran avantatge d'evitar la introducció de les comandes de text que necesita VEX perquè son substituïdes per elements. És una eina més intuïtiva, ràpida i eficient. JavaVEX mostra informació sobre el codi C traduït a instruccions VLIW de fins a 4 operacions. També mostra els resultats de les instrucciones VLIW simulades. JavaVEX s'ha incorporat a un LiveCD. Així es pot executar l'aplicació sobre qualsevol ordinador. La finalitat docent de JavaVEX és ser utilitzada en les pràctiques de l'assignatura Arquitectura per a Computadors 2.

La dépendance à l'égard de l'environnement lors de lésions cérébrales: conduites d'imitation, de préhension et d'utilisation [Environmental dependence in brain lesions: imitative behavior, prehension and utilization].

This paper reviews the literature on clinical signs such as imitation behavior, grasp reaction, manipulation of tools, utilization behavior, environmental dependency, hyperlexia, hypergraphia and echolalia. Some aspects of this semiology are of special interest because they refer to essential notions such as free-will and autonomy.
